The inner diameter of the pipe of the connecting end 5211 is smaller than the inner diameter of the pipe of the defoaming end 5212, which is equivalent to the occurrence of the necking part of the connecting end 5211 in the vent pipe 52, when the foam reaches the necking part of the connecting end 5211, the foam is subjected to pressure due to necking, a part of the foam is broken under the pressure and does not continue to advance to the defoaming end 5212, and the other part of the foam continues to advance to the defoaming end 5212 and is intercepted and broken by the defoaming end 5212.
Further, the inside of the defoaming end comprises at least one defoaming plate 5213, the defoaming plates 5213 respectively extend in the radial direction and the axial direction inside the defoaming end 5212, a gap for ventilation is arranged between the defoaming plate 5213 and the inner wall of the tubular body and/or between the defoaming plates 5213,
preferably, the defoaming plate 5213 extends from the interface between the connecting end 5211 and the defoaming end 5212 to the end of the defoaming end 5212,
more preferably, the defoaming plate 5213 is integrally formed inside the defoaming end 5212.
In the above scheme, the defoaming end includes a defoaming plate 5213 inside to prevent the foam from overflowing, the defoaming plate 5213 is radially disposed in the middle of the defoaming end 5212 and axially extends, in a preferred embodiment, the defoaming plate 5213 axially extends to the boundary between the defoaming end 5212 and the connecting end 5211, when the foam overflows from the connecting end 5211 to the defoaming end 5212, a part of the foam is firstly crushed by the necking part of the connecting end 5211, and the rest of the foam is crushed and then crushed again by the defoaming plate 5213, so that no foam overflows from the defoaming end 5212. The space between the defoaming plate 5213 and the inner wall is the space for ventilation, so that the defoaming structure 521 can prevent the foam from overflowing on the premise of realizing the ventilation function of the ventilation tube 52. The anti-overflow portion includes two piece at least defoaming boards 5213, defoaming board 5213 parallel arrangement each other or crossing arrangement, there is ventilative space between the defoaming board 5213, between defoaming board 5213 and the defoaming end 5212 inner wall, when the foam spills over from connecting end 5211 to defoaming end 5212, be earlier by the necking portion extrusion fracture of connecting end 5211 partly, the remainder is met defoaming board 5213 after being extruded and is broken by the extrusion once more, can not have the foam to spill over from defoaming end 5212.
